Question

Osteoid-producing osteoblasts must rely on this organelle to produce primary structures leading to the formation of collagen and calcium-binding proteins.

a. Peroxisomes
b. Ribosomes
c. Mitochondria
d. Centrioles

Answer 1

Osteoblasts rely on ribosomes to synthesize collagen and non-collagen proteins essential for bone formation. Ribosomes play a critical role in the synthesis of these proteins, which are part of the organic bone matrix that mineralizes into bone.

Step-by-step explanation:

Osteoid-producing osteoblasts need to rely on a certain organelle to produce the primary structures that lead to the formation of collagen and calcium-binding proteins. This organelle is the ribosome, which is essential for protein synthesis. Ribosomes are cellular structures responsible for the synthesis of proteins, necessary for the functioning and structure of body cells. In the context of osteoblasts, which are bone-forming cells, ribosomes facilitate the production of collagen, an integral component of the bone matrix, as well as other non-collagen proteins.

The process of bone formation involves osteoblasts secreting collagen and non-collagen proteins to form the organic matrix, which eventually mineralizes to become bone. Ribosomes play a critical role in this process by synthesizing the proteins required. Therefore, the correct answer to the question is b. Ribosomes.

Answer 2

The correct answer is option b. "Ribosomes".

Step-by-step explanation:

Osteoid-producing osteoblast must rely on ribosomes to produce the primary structures leading to the formation of collagen and calcium-binding proteins. Ribosomes are organelles whose main function is to produce proteins, therefore, this organelle is the one that must function in order to osteoid-producing osteoblast could produce the proteins that it needs.
